circulatory system (bloodstream) transports nutrients, oxygen and waste all over the body. The heart does this by beating, and pumping blood, keeping it moving.
blood is passed through the kidneys and waste (urea mainly) is filtered out, the blood goes back into the bloodstream, while the waste is passed on to the the bladder (urine).
liver cells have many enzymes, more than other cells, and can break down toxins like ethanol and hydrogen peroxide.
